Yeah it's a scam don't do it. They seem to go around and ask to fund multiple different games. A random person is just going to give that much money for no benefits in return? Yeah just a scam. If it's not I'd be surprised but it feels pretty obvious. People just don't do this. If they wanna do it then they can just donate it to you through a gofundme or something like that. Safest option for you and proves they really wanted to help. Be careful of people being to generous for no reason. Especially when they want to give money to so many other people.
